Species and populations are probably the two most commonly used ecology terms, but they are often difficult concepts to grasp. Throughout this chapter, they will be discussed in detail, expanding on the definitions from previous chapters and explaining why there are no universally acceptable definitions. Factors influencing population growth and ways to measure and predict population growth will also be subjects of specific focus. Populations can be affected by so many factors that it is almost impossible to take every variable into account. Demography is the statistical study of the age structure of a population, and it can be used in research to determine what is causing a decline or increase in population size over time. It is worthwhile to understand species concept and population growth even though they are such broad aspects, because they are fundamental to the science of ecology.

Species and population are two basic levels of classification of organisms in ecology. The other higher levels of classification include community and ecosystem. Both species and a population are composed of a similar type of individuals. The main difference between species and population is that species is a group of similar individuals who interbreed with each other whereas population consists of individuals of a particular species, in a specific region at a certain time. Any population may comprise genetic variations within the population and between other populations of the same species. Since individuals in a population interbreed with each other, no emergence of new species can be observed.

Distinguishing between a species and a subspecies can be difficult: most people are aware of the definition of a species, but when it comes to defining a subspecies , it can be a bit hazy and subjective. Technically, a species is a population or groups of populations that can potentially interbreed freely within and among themselves. This is a naturally-defined concept, something which exists by itself. Subspecies, on the other hand, are subgroups within a species that have different traits and are defined by scientists. The basic unit of this taxonomy is a species.

When we study the organisms, we know that all of the organisms in the world are classified through a hierarchy and are further broken down and named via binomial nomenclature. This is studied in biology as students explore all of the aspects of all living things from naming and classification up to the structures and body parts, these are all included. So biology can also be considered as a great and fulfilling career plus one of the best premedical courses.

Scientists have recognized that life can be organized into several different levels of function and complexity. These functional levels are: species , populations , communities , and ecosystems. Species are the different kinds of organisms found on the Earth. A more exact definition of species is a group of interbreeding organisms that do not ordinarily breed with members of other groups. If a species interbreeds freely with other species, it would no longer be a distinctive kind of organism. This definition works well with animals. However, in some plant species fertile crossings can take place among morphologically and physiologically different kinds of vegetation.

    A species is a certain unique type or organism in the entire biosphere, while a population is all of the members of a species in one ecosystem.
